| 摘 要： | 基于京津冀、长三角和珠三角三大城市群2007-2013年土地集约利用与城市化水平的测度,运用协整检验、脉冲响应和方差分解等计量方法,对其城市化与土地集约利用的动态关系和相互作用强度进行研究。结果表明：三大城市群土地集约利用与城市化水平之间存在长期的正向促进作用,但作用强度不同;城市化对土地集约利用的作用强度表现为京津冀>珠三角>长三角,而土地集约利用对城市化的作用强度则表现为长三角>京津冀>珠三角;京津冀和珠三角城市群应在城市化进程中加强城市土地的内涵挖潜,而长三角城市群应逐步调整和优化城市发展模式,从而实现三大城市群城市化与土地集约利用的协同发展。

| Abstract: | This study constructed an evaluation index system for urban land intensive use and urbanization based on their definitions. In addition, urban land intensive use and urbanization levels were measured in three urban agglomerations located in east China from 2007 to 2013 by the improved entropy method, which paves the way for the analyses such as co-integration theory, impulse response function and variance decomposition to explore the changing relationships and the interactions between urban land intensive use and urbanization. The analyses reveal that the levels of both urban land intensive use and urbanization are on the rise and there is a stable long-term equilibrium relationship between them. This indicates that they develop together and that each has a positive effect on the other in the long term. However, the specific effect that each has on the other is different. With regard to the impact of urbanization on intensive land use, the Beijing-Tianjin-Hebei urban agglomeration ranks first, while the Yangtze River Delta urban agglomeration ranks last. On the other hand, with regard to the impact of intensive land use on urbanization, the Yangtze River Delta urban agglomeration ranks first, while the Pearl River Delta urban agglomeration ranks last. Based on this, each of the three urban agglomerations should focus on different aspects in the future. The Beijing-Tianjin-Hebei urban agglomeration should focus on scientific land use planning and improving intensive land use level in order to enhance the effect of intensive land use on urbanization. Urban land intensive use generates a negative effect on urbanization and urbanization only exerts a weak influence on urban land intensive use in the case of the Yangtze River Delta urban agglomeration, but they will achieve harmonious development in the long term. Therefore, it is important to carry out reasonable urban planning, adjust the urbanization mode to realize sustainable urban development and enhance the effect of urbanization on urban land intensive use from a long-term perspective. The Pearl River Delta urban agglomeration ranks last in terms of the impact of intensive land use on urbanization. Therefore, it is necessary to focus on intensive land use theory and enhance the effect of intensive land use on urbanization in order to achieve harmonious future development. This is the only way to enhance the relationship between urbanization and urban land intensive use. In turn, this is the only way in which urbanization can be made sustainable and the theory of urban land intensive use be applied more reasonably, thus providing the foundation for the sustainable development of both. |
